Our take

Since CrowdStrike was founded by a trio of former McAfee executives in 2011, it’s grown into a thousands-strong, NASDAQ-listed company. With customers including Verizon, Deloitte, and Goldman Sachs, it’s considered one of the world’s top enterprise cybersecurity vendors along with the likes of Cisco, IBM, and Palo Alto Networks.

One of the reasons behind CrowdStrike's continued success is its ability to keep pace with the evolving tech market, for instance with its Generative AI security analyst that leverages recent developments in AI. Although not immune to the slowdown of the global economy, the company's modular design has given it the upper hand, allowing clients to consolidate their security spend with CrowdStrike instead of selecting packages from multiple vendors at a higher overall cost.

With long-term demand for cybersecurity products growing, and its reputation as strong as ever, CrowdStrike shows no signs of slowing down. It has partnered with Ignition Technology to double down on its UK presence, and continues to be a voice in the wider market through its "Falcon Fund" investment vehicle and position as a founding member of NIST's Artificial Intelligence Safety Institute Consortium (AISIC).
